Answer:
a rational number
Step-by-step explanation:
1) First, find the sum of [tex]\frac{4}{7} +\frac{-1}{3}[/tex]:
[tex]\frac{4}{7} + \frac{-1}{3} \\= \frac{12}{21} - \frac{7}{21} \\= \frac{5}{21}[/tex]
2) Any number that can be written as a fraction is a rational number. Therefore, the sum, [tex]\frac{5}{21}[/tex], is rational.
